KNOT TIER Q Filed Dec. 16, 1940 Patented July 8, 1941 re srss sexier FFICE 1 Claim.

This invention relates to knotting devices and more particularly to a manually operable device of improved and simplified structure, by means of which string may be rapidly and efficiently knotted around the folded ends of bologna, and the like.

The object of the invention is to provide means by which an operator can utilize a foot and supply substantially uniform knotting pressure while being relieved of the necessity for applying such procedure with his hands, which necessarily :become greasy and slippery in connection with handling such objects.

Various other objects will suggest themselves in the course of the following detailed description.

The invention consists in the novel construction, arrangement, and combinations of parts hereinafter more specifically described and claimed.

One sheet of drawings accompanies this specification as part thereof, in which like reference numerals indicate like parts throughout.

In the drawing Figure 1 is a side elevation of the improved device;

Figure 2 is a front view of the device;

Figure 3 is a fragmentary perspective illustrating the use of the device.

The particular embodiment of the invention illustrated shows a base I adapted to be secured to any suitable table, upon which are pivotally mounted as by bolts I2 two spaced vertically extending levers lI-I I, one of which is provided near its upper free end with a through guide hole It through which the string S to be used in the device is threaded while the upper end of the opposed lever II is provided with a slot I! also adapted to receive this string. The base I is provided with a central hole and bushing 2 within which is slidably positioned a rod 3 pivoted at its lower end as by bolt 4 to a pedal lever 5 pivoted at its rear end as by bolt 6 to an angle plate I adapted to be secured to the floor. The rod 3 is provided with a screw eye 8 positioned below base I and this screw eye 8 is connected as by spring 9 to a second screw eye It supported from base I. It will be apparent that the spring 9 will tend normally to raise rod 3 with respect to the base and elevate foot pedal 5. The upper end of rod 3 is bent laterally as at I5 and upon it are pivoted two links I3I3 which are pivoted respectively as by bolts I4-I4 to the spaced levers IIII. Near the upper end of the lever I I which has its upper end provided with the slot i1 is secured a knife I8 conveniently positioned for severing the knotted cord upon the completion of the knotting operation. The base .I also carries an upwardly directed spindle I9 adapted to receive a cone of cord 2%] and from which the string S is conveniently guided through the guide hole I6 in the adjacent lever II and thence through the slot I! in the opposed lever I I.

In operation the string S having been threaded through the hole I6 is cast in a single loop 2I around the free end of that lever to prevent further feeding of the string therethrough. The free end of the string is then passed into slot I1 and cast in oppositely directed small loops e-e around the folded end of the casing of the bologna. These loops should be cast as suggested in opposite directions to provide the efiective knot commonly known as a half-hitch. Pressure of the foot on the foot pedal 5 will depress rod 3 and links I3I3, thus forcing levers I I-I I apart and drawing the string S tau-t with uniform pressure on the doubled loops cast on the bologna casing. The pedal being released the levers IIII again draw together thus permitting the lowering of bologna to cut the string on knife l8 and the operation can be repeated with great rapidity and precision.

Various modifications in the precise construction and arrangement of the parts will readily suggest themselves to those skilled in this art but all within the scope of the present invention as claimed.

Having thus fully described my invention I claim:

A knot tightener comprising a base, two spaced members pivoted at their lower ends to the base and having their upper ends formed with string guiding means, a rod vertically slidable through the base, links connecting the upper end of the rod with said spaced pivoted members, spring means connecting the rod and base to normally elevate the rod and rock the spaced members towards each other, and pedal means for depressing the rod.
